FRANK B. PHILBRICK, OF WATERVILLE, MAINE, ASSIGNOR OF ONE-HALF TO 4FRANK B. XVEBBER, OF SAME PLACE.

CYLINDER PLANER.

SPECIFICATION forming part of Letters Patent No. 397,246, dated February5, 1889. Application filed August 1 l 1888. Serial No. 281,699. (Nomodel-) To all whom it may concern:

Be it known that I, FRANK B. PHILBRICK, a citizen of the United States,residing at Yaterville, in the county of Kennebec and State of Maine,have invented certain new. and use ful Improvements in Cylinder Planers;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

Myinvention relates to cylinder planersof that class commonly calledbuzz planers, which consist of a cyliiiider-head having a table on eachside whose upper surfaces are approximately on a level with the uppersurface of the cylinder-head, one or both being adjustable vertically.They are used for planing the surfaces of short pieces of lumber,rabbeting door-frames, and for other like work.

My invention is directed to the production of a planer which shallcombine cheapness, simplicity, and strength, and particularly to animproved construction of the bearings by which the cams which raise andlower the tables are connected with the standard and the brackets onwhich the table rests. Hitherto these hearings or parts of them havebeen detachable and separate parts of the machine, and, beingconstructed in the ordinary form, they were necessarily attached to thestandard by bolts or otherwise. By the use of my improvement I amenabled to cast the standard and its bearings all in one piece, and inlike manner the bed and its brackets and bearings are also cast in onepiece, thus saving much expense in finishing many parts and making mymachine very solid and durable.

My invention consists, essentially, in forming the standard and thebearings integral. The latter, instead of having a circular opening, asusually made, are open at the top for a space of less than thesen1i-circu1nference of the hearing. The brackets and their bearings arealso integral and have a similar constrnction, except that the openingis downward, the cams being sufficiently eccentric so that they can beslipped laterally into place, and when turned slightly will be locked inall directions.

The invention also consists of the various combinations of parts, ashereinafter set forth in the claims.

In the accompanying drawings I illustrate a machine which embodies myinvention, although I do not wish to limit myself to the exact featureshere shown.

In the drawings, Figure 1 is a perspective view. Fig. 2 is a sideelevation. Fig. 3 is an end elevation. Fig. 4E is an enlarged section onthe line a: a: of Fig. 5. Fig. 5 is a section on the line so a: of Fig.4.

The standard or support A is provided with the usual base. The lowerportion has its four sides continuous. Near its upper end the sidesdiverge to a considerably greater width than at the lower part, and theyalso extend outlengthwise of the machine to form the upper bearings, B13.

All the bearingsten in numberare cast in one piece with the standard.These consist of the bearings C for the cylinder-head at the extremeupper and central part, four bearings, 13 B, two on each side and nearthe top, and the four bearings B B near the bottom. The upper bearings Bdo not form complete circles, but they are open at the top for a spaceof less than a semicircle. They present in section the figure of acircular segment greater in area than half a circle, with the topportion cut away; The lower bearings have a similar opening at the top,except that they are made, preferably, as half-bearings, or nearly so.

The two tables 0 O and their supportingbrackets F F are cast all in onepiece, including the four bearings in each bracket. These brackets havea general triangular shape and are placed one under each side of itstable, and the lower ends draw together or approach each other to adaptthemselves to the width of the standard. The upper bearings f f on thebrackets are similar in construction to the bearings B B, except thatthe segmental opening is downward instead of 5 upward, and the two lowerbearings are in the form of a half-circle, or they may be made less thana half-circle.

The upper bearings, B and f, are adapted to fit the cams D and D, whichare identical 10o in form. Each of these cams is formed of: acylindrical bearing, d? and (7 (see Figs. 4 and 5,) the outer bearing,fitting the bearing B in the standard and the inner bearing, (1, fittingthe hearingf in the bracket. These two cylindrical portions of the camare formed integral and are eccentric as to each other, lapping, as hereshown, smnething less than one-half of a circle. Theamountwhich thesecircular sections overlap each other or the solid portion which joinsthem, is about equal in extent, as here shown,t:o the open spaeelc't'tin the bearings, that when the centers of the cam are in a verticalposition relative to each other, and the hearings are in a likeposition, the former can he slipped endwise \Yhen,how-

through the latterintoposition. ever, the cam is turnedv slightly ineither direction, the lateral outer surface of the inner section orhearing'eomes against the inner edge of the hearing ll of the stamlardand the inner lateral surface of the outer section, (I comes against thebracket. It. will thus be seen that when the cams are slipped in in a'vert ical position and then slightly turned they are locked against anylateral pressure in both directions, as well as any horizontal orvertical pressure.

The lower cams are similar in form to the upper ones and are titted tothe half-bearings .3 and f. Each pair of cams on opposite sides isunited by a shaft or arbor, L, (see I? g '11,) the shaft which unitesthe lower cams being much shorter than those which join the upper ones.Each shaft has formed integral with it, as here shown, a short arm orlever, (1 which pro j ects horizontally outward when the tables areraised, and the ends of the arms, which are vertically over each other,are connected by a link, E.

To the lower can], D at one side of the m aehine, is attached thehand-lever G. The lever is secured by passing through a slot in the faceof the cam to which it is bolted. The lower end of the lever G, which isbent to occupy a suhstantially-horizontal position, .is provided with acounter-weight, G. On the upper end of the lever G is a fixed handlc, g,and a pivoted handle, g,arrangcd side by side, in the usual manner. Aspring, g is inserted between them at their upper ends and acts to forcethem apart. A segment, ll, is pivcted, as here shown, to the outersection of the cam I) and passes through openings in the handles g andg.

The opening in the pivoted handle 9' cut away to form two pinching edgesor surfaces, one, above the segment and on the outside of the handle orthe side farthest from the spring, and one, g", on the under side of thesegment on the inside of the handle. At the end oi the segmenttherc is ahook or stop to limit the motion of the lever.

To the cam l), which supports the back table, there attached a shortarm, I, to the end of which is pivoted a nut, i. A screw,.J,

passes through the nut i, the end of the screw brackets.

being secured to a stud, J in such a manner that it is eapableot beingrotated. The stud J is pivoted. to the side of the machine and the screw.l provided with a hand-wheel, .l.

The machine is made up and may he put ttj gether in the followingmanner, namely: The hearings havingbemi properly faced and turned, theupper hearings in each bracket are placed in position in a verticalplane above the bearings in the standard. The upper cams are thenslipped in endwise, as he tore described, and the lower cams are simplydropped into place. in. their hearings, which is readily done, since thelatter are in form semicireular. The lower hearings of each bracket arenow brought to rest on the lower cams, and, finally, the link E isinsertetl, \v'liich locks all parts in position, so that they cannot hedisplaced. Segnuimtal shoulders 11" and (1 are formed lwtween thetwocam-hear ings (Z and d", Fig. 5, to take the hearing against'thetable and the standard and to save finishing the entire face of theearns. 'lhe lever (1 and the arm I are attached to the cams in anysuitable manner.

It will he seen that l anreiuthledby theuse of my improved structure tomake the main part of my machine practically in three piecesnainely, thetwo tables and the standard dispensing entirely with all detachablebearings both on the standard and on the This adds great strength andrigidity to the machine, among other things enablin g me to plane offthe tables or beds after the machine is set up, thus securing the mostexact alignment. The use of the lever G gives me quick control over thetable, and

d the clamp and segment render the nicest adj ustment possible.

It is evident that many changes and modifieations may be made in mymachine, as here illustrated. and exactly described, without dc partingfrom the spirit of my invention as expressed in the claims.

The device here shown and described for raising and lowering the reartable, F, and that for raising and lowering the front table, F, aredesigned to he used in one machine, they being especially adapted to therequirements of each case.
